Corridors are highly customizable and enable designers to integrate alignments, profiles, assemblies, and surfaces into a seamless design process. Here's a step-by-step guide on how to effectively use corridors in site design:
1. Understand the Role of Corridors in Site Design Corridors aren't limited to roadway design—they can be used to model:
Parking lots and driveways Sidewalks and pathways Grading for curbs, gutters, and drainage Intersections and roundabouts Retention basins and channel slopes Corridors are built from alignments (horizontal layout), profiles (vertical layout), and assemblies (cross-sectional design).
2. Create and Prepare the Site Plan Add Alignments:
Use alignments to define road centerlines, parking lot edges, or other site features. Go to Home Create Design Alignment Create Alignment from Layout to draw the desired geometry. Add Profiles:
Create profiles for each alignment: Go to Home Profile Create Surface Profile. Draw design profiles for road slopes, driveways, or parking lot grading. 3. Build Corridors Create a Corridor:
Go to Home Corridor Create Corridor. Select an alignment, a profile, and an assembly to define the corridor. Use Assemblies for Site Design:
Use pre-built or custom assemblies that match your site features: Road assemblies with curbs and gutters for parking lots. Sidewalk assemblies for pedestrian paths. Simple grading assemblies for berms or channels. 4. Model Transitions and Intersections Set Baselines for Transitions:
For areas like intersections or driveway entrances, add additional baselines to the corridor. Alignments and profiles for baselines should match the desired geometry of transitions. Use Region Targets:
Target surfaces, alignments, or feature lines for curb returns, lot grading, or driveway edges: Select the corridor, right-click, and choose Corridor Properties. In the Parameters tab, set targets for regions like width or elevation. 5. Incorporate Site Grading Create Corridor Surfaces:
In Corridor Properties, go to the Surfaces tab and create a Top surface or any other required surfaces from the corridor. These surfaces represent the finished grade of your site. Combine with Feature Lines:
Extract feature lines from the corridor to refine grading for specific areas like islands or boundaries. Use the Grading Tools to slope parking lots, retention basins, or pathways. 6. Analyze and Optimize Volume Calculations:
Use the corridor to calculate earthwork volumes for cut and fill analysis. Go to Analyze Volumes and Materials. Check Grading:
Use the Section Editor to review cross-sections for proper drainage and compliance with design requirements. 7. Visualize the Site Design 3D Visualization:
